Refer to the following calculation when Pr.06-30 is set to 23% and motor temperature overheating
protection level is 1330 Ω:
1330//20000 = (1330 × 20000) ÷ (1330+20000) = 1247.07
10.5 × 1247.07 ÷ (4400+1247.07) = 2.32 (V) ≒ 2.3 (V)
Pr.06-30 = 2.3 ÷ 10 V × % = 23%
Frequency Command at Malfunction
When a malfunction occurs, check the current Frequency command. If it happens again, it
overwrites the previous record.
Output Frequency at Malfunction
When a malfunction occurs, check the current output frequency. If it happens again, it overwrites
the previous record.
Output Voltage at Malfunction
When a malfunction occurs, check the current output voltage. If it happens again, it overwrites
the previous record.
DC bus Voltage at Malfunction
When a malfunction occurs, check the current DC bus voltage. If it happens again, it overwrites
the previous record.
Output Current at Malfunction
When a malfunction occurs, check the current output current. If it happens again, it overwrites
the previous record.
IGBT Temperature at Malfunction
When a malfunction occurs, check the current IGBT temperature. If it happens again, it
overwrites the previous record.
